Subject [jira] Reopened: (CAY-1235) Implement qualifiers for DBEntities
Date Wed, 17 Jun 2009 07:30:07 GMT

     [ https://issues.apache.org/jira/browse/CAY-1235?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrey Razumovsky reopened CAY-1235:
------------------------------------


Turns out we need some type of expressions for DBEntities, to correctly insert table prefix
to a db entity qualifier, e.g.
SELECT .... from p1 .... WHERE p1.deleted=false 
instead of 
SELECT .... from p1 .... WHERE deleted=false 

> Implement qualifiers for DBEntities

> This is much like ObjEntities qualifier, only applied on DBEntities level. This, for
instance, means that it will be inserted in needed JOINs of any select, thus allowing to use
restricting qualifiers in e.g. middle table of many-to-many flattened relationship.
> This issue includes core changes and modeler support
